LOL ( i like the timing trick) the timing trick works if it doesn't fail by much, if you undo your egr you're gonna fail miserably on NOX but what will it matter since if you're turbo you don't want a catalytic converter anyways. personally i wouldn't disable my egr system because i wouldn't want spark knock when the cylinder head temp goes up, if you want more power there's much safer ways to get it, than a couple horses here with a bigger risk of frying motor not built to handle much boost in the first place.
